Golf and tennis go so well together, so it's no surprise it works in love too! Even though pro Irish golfer Rory McIlroy and Danish tennis dynamo Caroline Wozniacki have recently denied engagement rumors, they're still a match made in sporting heaven. McIlroy even credits his girlfriend's work ethic for helping him get a new perspective on his career.

"Seeing how hard she works and how hard she practices and how dedicated she is, it definitely flipped a switch with me that I could be a little more like that," he's says. "She's definitely been a great influence on me."

Aaron Ross and Sanya Richards-Ross

There's no question Olympian Sanya Richards-Ross and NFL-er Aaron Ross have one incredible bond. The dynamic duo, who met as students at the University of Texas at Austin in 2003, married in 2010 and have never been stronger!

"If someone asked me if I believed in love at first sight before I met Sanya, I would kind of think it was like a fairy tale," Ross told the Florida Times-Union. "But from the first time I've seen her, I wanted her. I've been wanting her even more ever since." Aw!

So how do they stay in pro-form all year long? Aside from sports, Richards-Ross helps her hubby eat right (no junk food allowed), along with calorie-burning, sweaty sessions like running, squats, and lunges.

The couple that works out together, stays together! At least that's the case for Olympic beach volleyball player Misty May-Treanor and her husband, Dodgers catcher Matt Treanor. After meeting in 2003 at a sports therapy center, the happy couple married just one year later.

One secret to their lasting relationship? They share a track coach! "We're workout partners, so we motivate each other in the gym and on the track," Misty said during a Countdown to London webcast. "I want to see him achieve great things… what's your goal? What's my goal? How can we help each other make that happen?" Gotta love that!

Ashton Eaton and Brianne Theisen

If you're looking for an Olympic power couple, you can't do much better than Ashton Eaton and Brianne Theisen. The college sweethearts are engaged and both incredibly talented as world-class track and field stars. After setting records in sprinting, running, throwing, hurdles, and jumping, we can't wait to see what their kids can do!

"I can't remember when I wasn't running around doing some sort of a sporting activity," Eaton revealed to Men's Health. "When you're doing any event on an elite level, you're in tune with your body." These two lovebirds are surely in tune with each other, too!

Bode Miller and Morgan Beck

For US ski champion Bode Miller and pro volleyball player Morgan Beck, it seems to be love at first sight; the talented twosome met in May of 2012 and married just five months later!

The 35-year-old New Hampshire native is known for a go-for-broke style on the slopes that's resulted in 33 World Cup wins and five Olympic medals, so it's no surprise he worked hard to win Beck too. "I have found the one!!! And convinced her to marry me. It was a process, Morgan Beck is hard to convince," he tweeted back in September. I think we can all let out a collective, "aww."

A.J. Feeley and Heather Mitts

Gorgeous soccer star Heather Mitts and her handsome husband, former Eagles QB A.J. Feeley, definitely make one fit dream team. The powerful pair dated for seven years before getting married in Cabo San Lucas, Mexico in 2010. It's their job to stay healthy, so it makes sense that the busy couple always makes time for their workouts. Mitts stays in tip-top shape training 11 months of the year, practicing twice a day, six days a week for two hours. When she's on the road, the soccer hottie packs her TRX but admits to loving her desserts.

Laird Hamilton and Gabrielle Reece

It's impossible to omit former pro beach volleyball player Gabby Reece and her hunky big wave surfer hubby Laird Hamilton from any list of hot, fit couples. The healthy duo, who have been married since 1997, stay in such awesome shape by exercising in their pool and cycling. But working out together doesn't come easy. "I always joke that we are both too bossy to train together—trying to tell each other what to do, and he always wins," Reece told FitSugar. "I would say Laird is far more advanced in some of the things he is able to do. I use him as an inspiration."

Marko Jaric and Adriana Lima

Victoria's Secret stunner Adriana Lima and basketball star Marko Jaric met in 2006 and wed in February 2009, with their first daughter born later that year. Apparently, Brazilian Lima knew she wanted to settle down with him the moment they met. "I knew he was the one—I could see myself married to him and with a big family," she's said. Talk about a model couple!

No stranger to working hard for those bods, they're both known for sweating up a storm in the gym; Lima infamously worked out twice a day, seven days a week to hit the runway just eight weeks after giving birth to their second child.

Andy Roddick and Brooklyn Decker

Though she initially ignored tennis champion Andy Roddick's requests for a date, model-turned-actress Brooklyn Decker soon realized she had a major score! How did she know he was the one after five months? "He made me laugh—he is hilarious and he is also chivalrous," Decker says. No doubt, Roddick is attracted to her traffic-stopping body, which she keeps in sexy shape by hitting the gym five days a week for hour-long sessions of cardio, abs moves, and weight training.

Cristiano Ronaldo and Irina Shayk

He's a gorgeous Portuguese footballer and she's a Russian supermodel. Let's just say, Cristiano Ronaldo and Irina Shayk make one smoking hot couple! The good-looking pair have been dating since 2010 and are clearly dedicated to keeping their bodacious bods in top form.

Case in point? Ronaldo practices five times a week for three to four hours per day while following a strict diet plan, and Shayk recently told Vogue, "I have good genes, which helps, but you have to be tough. I'm not a lazy person and I push myself. I go to the gym three or four times a week when I'm not traveling."
